you can get all needed files from the following two links. The second archive contains some "extensions" to the C++ standard libraries I found very useful to have.
I haven't bothered with a license yet, but I definitely want it to be open source and free.
Because I'm developing on Windows there are unfortunately no make-files and also very little documentation at the moment. But if there are any questions or suggestions please to not hesitate contacting me.
